E hoʻomaopopo i nā ʻano magnetism 7: ʻO ke kuleana o nā magnet ikaika.

He mana koʻikoʻi ka Magnetism i loko o ke ʻano e hana nui i nā noi ʻepekema a me ka ʻenehana. Aia ma ka puʻuwai o nā hanana magneticmagnets, ʻoi akunā magnet ikaika, nona nā waiwai kū hoʻokahi i hiki ke hoʻokaʻawale ʻia i ʻehiku mau ʻano magnetic like ʻole. ʻO ka hoʻomaopopo ʻana i kēia mau ʻano hiki ke hoʻonui i ko mākou ʻike i ka hana ʻana o nā magnet ikaika a me kā lākou noi i ke ola o kēlā me kēia lā.

1. Ferromagnetism: ʻO kēia ka mea maʻamau o ka magnetism, a me nā mea e like me ka hao, cobalt, a me ka nickelmanaʻo ikaika. Hiki i nā magnet ikaika i hana ʻia mai kēia mau mea ke hoʻopaʻa i ko lākou magnetism ʻoiai ma hope o ka nalo ʻana o ke kahua magnetic waho.

2. Paramagnetic: Ma keia 'ano, he mea nawaliwali ka hoohuoi i ke kahua magnetic. ʻAʻole like me nā mea ferromagnetic, ʻaʻole paʻa nā mea paramagnetic i kā lākou magnetism ma hope o ka nalo ʻana o ke kahua magnetic waho.Mākēneki ikaikahiki ke hoʻopili i kēia mau mea, akā he manawa pōkole ka hopena.

3. Diamagnetism: Hōʻike nā mea a pau i kekahi degere o nā waiwai diamagnetic, kahi ʻano nāwaliwali loa o ka magnetism. Hiki i nā magnet ikaika ke hoʻokuʻu i nā mea diamagnetic, i kekahi mau mea e hoʻoneʻe iā lākou, e hōʻike ana i kahi pilina hoihoi onā mana hoʻokalakupua.

4. Antiferromagnetism: I loko o nā mea antiferromagnetic, pili nā manawa magnetic e pili ana i nā ʻaoʻao ʻē aʻe, e kāpae ana kekahi i kekahi. ʻAʻole kēia hopena i ka magnetization ʻupena ma ke alo o amagnet ikaika.

5. Ferrimagnetism: E like me ka antiferromagnetism, loaʻa nā mea ferrimagnetic i nā manawa kuʻekuʻe, akā ʻaʻole like lākou, e hopena i ka magnetization upena. Hiki i nā magnet ikaika ke launa pū me kēia mau mea, e hoʻohana pono iā lākou i nā ʻano hana like ʻole.

6. Superparamagnetism: Loaʻa kēia hanana i nā nanoparticles ferromagnetic liʻiliʻi a i ʻole ferrimagnetic. Ke hōʻike ʻia i kahi magnet ikaika, hōʻike kēia mau ʻāpana i kahi magnetization i haʻi ʻia, ʻoiai inā ʻaʻole i loaʻa kahi māla magnetic, nalowale ka magnetization.

7. Supermagnetic: Hōʻike kēia ʻano i nā mea maʻamau ʻaʻole magnetik akā lilo i mea hoʻokalakupua i ka wā e ʻike ʻia ai i nā māla magnetic ikaika.

I ka hopena, ʻo ke aʻo ʻana i ka magnetism, ʻoi aku ma o ka lens o nā magnet ikaika, hōʻike i kahi honua paʻakikī a hoihoi. Loaʻa i kēlā me kēia ʻano magnetism nā waiwai kūʻokoʻa a me nā noi e pono ai no ka holomua o ka ʻenehana a me ka ʻepekema waiwai. ʻO ka hoʻomaopopo ʻana i kēia mau ʻano, ʻaʻole ia e hoʻonui i ko mākou ʻike no nā phenomena magnetic akā wehe pū kekahi i ka puka i nā noi hou o nā magnet ikaika ma nā ʻano āpau.
